It’s the last one. b < c < a
Complementary angles are angles who sum to 90 degrees. So, since one angle is 13 degrees, naturally the other must equal 77. Good luck! c:
A shape with 4 angles always have 360 degrees altogether.
Which means:
43 + 167 + 90 + y = 360
y = 360 - 43 - 167 - 90
y = 60
Parametric form.....
y=3x+ 1/4z
